The Dakota Radio Group reports that Pierre, S.D. is installing LED street lights.
The story says that the LEDs being used consume about 45 percent less energy than the lights they are replacing. Recently, 35 of the new fixtures were installed in the city’s Fourth Street. The annual savings from those LEDs is expected to be $1,250 annually. About 100 fixtures so far have been replaced.
The story says that the new lights have a lifespan of as long as 50,000 hours, which is five times longer than the legacy lights. The city electrical utility, which is doing the installation, serves more than 7,300 residents.
The migration to LEDs can be a long and complex one, according to Vac-Con Continuous Improvement Manager Bill Barnes.
